Question 8 of 25
Which of these actually lowers a person's BAC?

Which sign shows a customer is losing coordination?
- Stumbling, swaying or spilling drinks
- Using their phone

Question 22 of 25
A customer shows a driver's license that expired last year. What is the safest choice?
- Accept it if they are with friends
- Accept it because the photo matches
- Accept it if they tip well
- Do not accept it and ask for a valid ID
Show answer
Answer: D. Do not accept it and ask for a valid ID
Many states and most employers require a valid, unexpired ID. Expired cards are easier to misuse.
Question 23 of 25
After you cut off a customer, who should you tell?
- Only the kitchen
- Your manager and co-workers

Letting the team know stops the customer from getting alcohol from another server or bartender.
